SPECIFICATION forming part of Letters Patent-N0. 702,795, dated June 17, 1902.

lApplication'tiled November 1,1399.`- Serial No. 735,495. (No model.)

To all whom, t m/wyiconcern: l

Be it known that I` IsAAo V. HOLMES, a citizen of the United States, residing in and whose post-office address is the city'of Chicago, in the county of Cook and` State ofIllinois, have invented certainnew an'duseful Improvements in.Centrifugal Separatorsg' of which the following is a speciiication. 'l

i Referring to the accompanying drawings, wherein like reference -letters yindicate the same or corresponding parts, Figure 1 is a vertical axial section of one form of my device. Figs. 2, 3, andA: are horizontal sections` taken, respectively, on lines 2 2, 3 3, and 4 4:

of Fig. 1 and viewed in the direction'in'di` cated by the arrows at the sides of said lastmentioned figure. Fig. 5 is a sectional view similar to Fig. l, showing 'a modification in that the inclosing casing Y is omitted and the. upper and lower ends of the revoluble drumA B are seated in suitable stufflnglboxes.

My invention relates to devices for the sepa-y ration of foreign matters from liquids, audit' particularly relates todevices forfpurifyi'ng water to be used for purposes of steam generation; and its object is' to produce aseparator which will in operating effectively eliminate from liquid matters held in suspensionv and solution therein; and to thatend-itcon# sists in the features of construction and, com

bination to be hereinafter more particularly described, and pointed'out i'n'theclaims'hereto annexed.

I will herein describel my device and its'opv-.I

eration in connection with the use forlwhich it is particularly designed--namely, forpuriv fying water for purposes of steam generation; but it will be understood that I in no manner limit it to said use, as it may be employ/edito separate foreign matters from licluidfh either for the purposegof utilizing said liquidth'usV purified or the eliminatedmatters. -Therefore indescribing its particular use the term water wherever employed herein shall'signify any liquid.

Referring to the drawings, A is an intakel passage communicatingat one end vwith any suitable source of water-supply and at its other end with the drum B; C, partitionwalls rigidly secured to the outer` wall b and the inner wall or hub b of the drum and dilviding it into separate chambers for a portion lof its length; D, an annular outlet-passage formed by the wall b ofthe drum and the outer wall of the'annular base-piece b2, said passage communicating at its upper end with the interior of the drum and at its lower'end with theya'nnular passage d; cl', a dischargelport communicating with the passage d and any suitable receptacle; E, an annularoutlet-passage formed by the 'end b4 of the hub b' of the drum and the inner wall of the annular I base-pieceb2 and communicating at its upper end with the interior of the drum and. at its lower end with the` bowl-shaped chamber F; f, fixed wings Within the chamber F, by means ofvwhich and the top f' tne chamber F, which ,communicates with the passage J, is rigidly 'secured to the walls of the concentric tubes "forming passages J K,abou`t the walls of which 'passages the drum B revolves; G, a spiral passage formed by the wallg and the worm H;

I, a receiving-chamber communicating with 4 the" spiral passage G and the discharge-pas- 4sage t," la, apertures in the walls of the pasrsage K and communicating with the interior of lthe drum and the'passage K, which passage at its upper end may communicate with vany suitable receptacle; b3, a bowl-shaped member secured in any suitable manner to ings; c, binding-pieces by means of which i =and the bolts c' the drum is revolubly secured to the base-piece b2.

It will be seen that the drum B, the basepiece b2, the bowl-shaped member b3, and the Wallg are rigidly secured together and revolubly mounted upon the bearingsM.

' As one of the essential features of my device is that it operates under internalpressure, and since in the construction shown in Fig. l

there will be some escape'around `tl1`e 'ends of the drum B, I vtherefore inclose the upper revoluble parts in a casing Y, adapted towithstand said pressure; but it is obvious that, if desired, that part of the casing which IOO surrounds the drum may be omitted and the drum be tted at its top and bottom into suitable stuffing-boxes.

I will now describe the operation of the device. Assuming the driving-shaft L and its connected parts to be revolving and the drum filled with heated water, when additional heated water enters the drum B from any suitable source, as through the passage A, it will be centrifugally acted upon, which action will to a certain extent cause the impurities in the water which are of greater specific gravity than the water to move toward the outer wall of the drum and the free air, gases, and impurities which are of. less specilic gravity to be moved toward the center of the drum-that is, toward the apertures 7tin the Walls of the passage Kthrou gh which apertures they will pass and be nally discharged from the passage K in any suitable manner from time to time, as by blowing out the purifier through said passage. NOW assuming the heavier impurities to lie at or approximate to the periphery of the drum,

ythe lighter impurities to be escaping from the drum through the apertures 7c, and the water lying between said periphery and the hub D to be pure, then by virtue of the pressure occasioned by the incoming water through the passage A the heavier impurities and a very small proportion of Water will be forced downwardly against the outer wall of the drum, from whence they will escape through the passage D into the passage d, from which they will be discharged through the port d', While the purified water, being subjected to the same pressure, will be driven from the drum through the passage E into the Xed chamber F, where it will'comein contact with the fixed wingsfand its rotary motion be at oncearrested. From this chamber F the purged liquid will enter the spiral passage G, the revolution of the worm H and the pressure referred to causing it to be forced through the passage I, whence it will be discharged through the passage t'. As the sudden arresting of the circular motion of the water within the fixed chamber F by the Walls fviolently disturbs it, causing it to froth, I have provided the passage J, communicating with the chamber F, through which passage said froth and such lighter impurities as Were not discharged through the apertures 7.: may be discharged.

The operation of the parts of my device when cold water is employed is the same as the operation when hot water is used so far as all matters held in suspension are concerned; but the matters held in solution remain in solution, the application of heat being necessary to cause foreign matters and gases in solution to become in suspension, the use of hotwaterwith my device or the application of heat to the water being therefore obviously preferable.

It will thus be seen I have provided in a separator means for eliminating foreign matters from hot or cold water, which matters have a greater or less specific gravity than the water and are held in suspension therein, and means whereby when hot Water is employed or the water employed be subjected to the influences of heat the gases and free air therein will be eliminated therefrom, thus causing the matters which were held in solution in the water to become in suspension, following which they will be eliminated therefrom in precisely the same manner as they would have been had they originally been in suspension.

Again referring to the drawings, c2 is akey adapted to secure the wing C within a suitable slot (indicated in Fig. l in dotted lines) in the hub 11'; N, clean-cut plugs or caps; M, an oiling port or passage; Z', an oiling port or passage through which oil may be communicated to the packing Z2; b5, a bolt.

It will be understood that whereas I have described one form of device in which the principle of my invention may be embodied l in no manner limit myinvention to that eX- act form, as it is obvious that the number, size, and form of the parts thereof may be greatly varied without departing from the principle of the invention, and it will be further understood that the expression lighter impurities wherever employed herein shall signify free air, gases, vegetable liber, and other impurities of less speeic gravity than the liquid within which they are contained.
